This new documentary special – part biography, part concert and performance retrospective – covers the 50-year career of Cat Stevens, the musician whose contributions to the film Harold & Maude, and his hugely popular introspective singer-songwriter LPs of the early Seventies, briefly put him at the top of the pop music business. Then he quit, to focus on his family and his faith, converted to Islam, and changed his name to Yusef. He returned to music, and recording, in the 2000s, and A Cat’s Attic covers all those changes, and a lot of the music. Included: “Father and Son,” “Peace Train,” “Tea for the Tillerman,” “Into White,” “Wild World” and “Moonshadow.” If none of those songs rings a bell, you’re either very young, or very old.
